I was in the South Point casino recently. In the hallway leading to the gift shop, they had a new machine (to me) made by AGS Gaming. A 3-seat console, with lighted display behind the 3 machines. The unit is about 8 ft. x 8 ft. and so bright, you might get a sunburn if you sat there very long!

There's lots of other super-sized slot machines / consoles on the floor these days, though I still like the basic ones best, mostly.
